Safety-Critical RTOS Support Extended for Microsemi’s SmartFusion2 SoC FPGAs01 Jul, 2013
Bristol, UK –July 29, 2013– WITTENSTEIN high integrity systems (WHIS), a leading safety systems company, extends SAFERTOS® support to the ARM® Cortex™ M3 microcontroller hard core embedded into Microsemi Corporation’s SmartFusion®2 SoC FPGA.
SAFERTOS™ is a safety certified Realtime Operating System that delivers performance and dependability to safety critical applications, whilst utilising minimal resources. The SmartFusion2 SAFERTOS variant is tightly integrated with the embedded microcontroller, including its MPU, allowing applications to be partitioned into logical segments according to their Safety Integrity Level (SIL). Commercial grade middleware can for example be used in conjunction with safety critical code, with isolation being achieved via the MPU.
SAFERTOS is supplied with a Design Assurance Pack which contains every design artifact produced during the full IEC 61508-3 life cycle. These will include development and safety life cycle plans, requirements, specifications and design documents, HAZOPS, source code, all verification and validation documents and related evidence. This can significantly smooth the path in achieving product certification.
“Integrating SAFERTOS onto the microcontroller embedded in Microsemi’s SmartFusion2 SoC FPGA results in an embedded platform designed to meet the stringent requirements of IEC 61508 SIL-3,” said Andrew Longhurst, engineering manager for WHIS. “This significantly reduces risk and project schedules in safety-critical developments, freeing engineers to work where they add the most value – on the application.”
Microsemi’s next-generation SmartFusion2 SoC FPGAs are designed to address fundamental requirements for advanced security, high reliability and low power in critical industrial, defence, aviation, communications and medical applications. SmartFusion2 integrates inherently reliable flash-based FPGA fabric, a 166 megahertz (MHz) ARM Cortex-M3 processor, advanced security processing accelerators, DSP blocks, SRAM, eNVM and industry-required high-performance communication interfaces all on a single chip.
“SmartFusion2 devices are a best-in-class solution for implementing safety critical, high-reliability designs. The advanced security features available in SmartFusion2 devices help create the secure life cycle on which high-reliability implementations ultimately depend. By providing safety-critical RTOS support for SmartFusion2 FPGAs customers now have increased the ease of development, ease of safety certification, and accelerated time to market for safety critical systems,” said Paul Ekas, vice president of marketing at Microsemi’s SoC Products Group.
WHIS provides full support for USB, FAT and TCP/IP for the SmartFusion2 hard core microcontroller.
SAFERTOS is available pre-certified by TÜV SÜD to IEC 61508-3 SIL-3 and is suitable for use in developments requiring certification to IEC 61508 and domain-specific adaptations, IEC 62304 class C and FDA 510(k) for medical, and DO 178B for aerospace.
